I have to do a simple backup task to DVD-R using flexbackup on Linux 2.6. My first idea was to use packet writing: setup the media, mount as rw somewhere and write to it.
So I installed udftools (Debian package, version 1.0.0b3-12) and started to read docs. README.Debian states:
3) Write an empty session spanning the whole medium. It seems that
without this step, any attempt to create the UDF filesystem will fail.
DVD-RW: growisofs -Z /dev/hdc=/dev/zero
If applied to a non-rewritable media THIS PRODUCES A NICE COASTER!
Ok, just skip this step and go to the next, which should be
mkudffs --udfrev=0x0150 --spartable=2 --media-type=dvd /dev/pktcdvd/0
but
this does not work, with error
trying to change type of multiple extents.
In short, unless I'm missing something, this means YOU CANNOT USE UDF FILESYSTEM ON DVD-R MEDIA ON LINUX 2.6. Go for cdrecord/growisofs and ISO.
